Thousands of illegals overran the Rio Grande sector of the border on Saturday, which continued a trend the sector’s chief, Ronaldo Karisch, described for the U.S. Senate’s Homeland Security Committee a month ago.

The inability of the government to control the border and its policy of catching and releasing illegals after they present themselves to border agents are two reasons the migrants from Central America won’t stop coming.

Border Patrol agents must be exhausted, and perhaps ready to surrender and head for home. The crisis, border officials have rightly said, is “unsustainable,” and what border agents encountered in the last three days shows how unsustainable it is.

A judge and trial court officer in Massachusetts helped an illegal alien escape from Immigration and Customs Enforcement last year, federal prosecutors allege, and they now face multiple charges, including conspiracy and obstruction of justice.
